Fig. 3From: Oscillations of Cerium Oxidation State Driven by Oxygen Diffusion in Colloidal Nanoceria (CeO2 − x )The stages of the nanoceria interaction with oxidant and water molecule. a Double-oxidized Ce4+–\( {\mathrm{V}}_{\mathrm{O}}^{++} \)–Ce4+ site and single-oxidized Ce4+–\( {\mathrm{V}}_{\mathrm{O}}^{+} \)–Ce3+ site on nanoceria surface and their interaction with H2O molecule. b Regeneration of Ce3+–VO–Ce3+ site for next oxidation cycleBack to article page
